Development Of Light Weight Concrete


By Dhawal Desai IIT Bombay ABSTRACT  This paper deals with the development of two types of lightweight concrete the one using lightweight aggregate (Pumice stone) and the other water floating type using Aluminium powder as an air entraining agent. This also shows the importance of water/cement ratio as in first type of concrete it relates to the smoothness of the surface and in second one it is a major factor which controls the expansion of concrete. INTRODUCTION:  Lightweight concrete can be defined as a type of concrete which includes an expanding agent in it that increases the volume of the mixture [...]

Joint Sealants


By:Deepak Kanitkar DGM – Technology & Business Development Chembond Chemicals Limited, Mumbai. One of the most essential materials for making the Building Envelope waterproof is the joint sealant. Joints are there invariably in all civil constructions. According to material of construction, there are different kinds of joints. Some are only for joining, some are for accommodating the movements. Movements are mainly because of thermal gradients caused by temperature variations. There are also movements due to seismic activity, settlement, shrinkage, creep and dynamic loads, temperature variations due to processes etc. All joints which are formed due to above reasons must be properly [...]
